Chow Yun-Fa, known as “I Love You Milkis” to his fans, has recently been the subject of health rumors. There were reports suggesting that he had suffered a stroke after being diagnosed with COVID-19. Chow Yun-Fat is a renowned figure in Hong Kong’s noir action films of the 1980s and is also beloved in Korea, where he goes by the nickname “Big Brother.”
Fans were left shocked by the news of the stroke. However, Chow Yun-Fat put the rumors to rest by attending the Busan International Film Festival, proving that his health was not compromised. This incident sheds light on the seriousness of strokes, which can be life-threatening. To gain a better understanding of strokes, let’s turn to the expertise of Professor Seung-Hoon Lee from Seoul National University Hospital’s Department of Neurology, who will share his insights on “Seoul National University Hospital Health TV.”
First and foremost, it is important to clarify the name of the condition. Sometimes, some people mistakenly refer to it as “stroke” instead of “apoplexy.” The correct term is “stroke.” Professor Seung-Hoon Lee explains that the addition of the word “jeung” after the disease’s name often leads to this confusion.
The main cause of a stroke is the disruption of blood flow to the brain cells.
A stroke is essentially a sudden breakdown of the brain. According to Professor Seung-Hoon Lee, “The ultimate cause of the brain’s sudden damage is the disruption of blood flow, which can be considered as the food supply for the brain cells.” When brain cells die suddenly, neurological symptoms occur, and this is what we refer to as a stroke.
There are two main types of strokes: cerebral infarction, which occurs when a blood vessel in the brain is blocked, and cerebral hemorrhage, which occurs when a blood vessel bursts in the brain. Globally, approximately 85% of strokes are cerebral infarctions, while the remaining 15% are cerebral hemorrhages. This shift towards cerebral infarctions is attributed to the Westernization of eating habits.
Which of the two types of strokes is more dangerous? While both cerebral infarction and cerebral hemorrhage require serious attention, the medical community classifies cerebral hemorrhage as the more severe condition. In Korea, the death rate from cerebral hemorrhage is relatively lower, around 20%, but globally, it ranges from 40% to 50%. Interestingly, Western countries have a higher death rate from cerebral hemorrhage, primarily due to genetic factors.
What symptoms and problems does a stroke cause? Stroke symptoms manifest locally. Cerebral infarctions only affect a part of the brain, resulting in localized neurological symptoms such as sudden limb paralysis on one side or loss of language function among other cognitive functions.
Previous discussions mentioned genetic factors as a reason for the higher death rate from cerebral hemorrhage in Western countries. It raises questions about whether family history is a crucial risk factor.
Surprisingly, Professor Seung-Hoon Lee’s perspective on this matter is to “disregard family history.” However, there are two genetic diseases related to strokes that require awareness of family history, namely, Cardasil disease and Moyamoya disease, as they can be inherited.
High blood pressure is a significant risk factor for both cerebral infarction and cerebral hemorrhage.
The lenient stance on family history is due to stroke being a condition that becomes more prevalent with age and aging. Additionally, there are five well-established risk factors for stroke that need attention. These include hypertension, hyperlipidemia, diabetes, tobacco use, and alcohol consumption. Among these, high blood pressure is a particularly high-risk factor for both cerebral infarction and cerebral hemorrhage. Diabetes and hyperlipidemia play more significant roles in cerebral infarction than cerebral hemorrhage. The cold weather’s association with increased danger is attributed to elevated blood pressure during such conditions.
Professor Seung-Hoon Lee emphasizes that individuals often contribute to their own strokes. Neglected factors such as smoking and alcohol consumption can have adverse effects. Interestingly, while alcohol consumption can be protective against cerebral infarction, it serves as a strong risk factor for cerebral hemorrhage. Consequently, when patients with brain infarctions inquire about their alcohol drinking habits, Professor Seung-Hoon Lee advises moderation. Ultimately, it is crucial to control the five risk factors, including alcohol, by managing high blood pressure, hyperlipidemia, and diabetes, as well as quitting smoking.
Professor Seung-Hoon Lee states, “Stroke is not an isolated occurrence but rather the result of various diseases.” Therefore, it is essential to conduct a detailed diagnosis and implement daily management strategies to mitigate these risk factors.

Chow Yun-Fa (Chow Yun-Fat), known to domestic fans as “I Love You Milkis,” has been the subject of rumors about his health recently. There was news that he had suffered a stroke after being diagnosed with COVID-19. Chow Yun-fat was a leading figure in the heyday of Hong Kong’s noir action films in the 1980s, and was also well-loved in Korea, where he was dubbed ‘Big Brother.’
Fans were shocked when they heard the news of the stroke. Fortunately, Chow Yun-Fat attended the recently held Busan International Film Festival and proved that the rumors about his health were fake news. That is why stroke is a fatal disease. Let’s take a look at the stroke revealed by Professor Seung-Hoon Lee from the Department of Neurology at Seoul National University Hospital through ‘Seoul National University Hospital Health TV’.
I think we should clarify the name first and move on. Sometimes, there are people who mistake ‘stroke’ for ‘stroke’. The correct name is stroke. Professor Seung-Hoon Lee explains that because the word ‘jeung’ is often added after the disease, it is sometimes mistaken for a stroke.
The cause is blood vessels that supply brain cells.
A stroke is simply a disease where the brain breaks down suddenly. Professor Seung-Hoon Lee explains, “Ultimately, sudden damage to the brain is caused by blood vessels, which can be considered the food supply (brain cells),” and “The neurological symptoms are called which occurs when brain cells die suddenly in a stroke.”
Stroke is further divided into cerebral infarction, which occurs when a cerebral blood vessel is blocked, and cerebral haemorrhage, which occurs when a cerebral blood vessel bursts. Worldwide, approximately 85% of strokes occur as cerebral infarctions, and the remaining 15% occur as cerebral haemorrhages. It is said that the reason for the low rate of cerebral hemorrhage is because the number of cerebral infarctions has increased along with the westernization of eating habits.
So which of the two is more dangerous? Of course, cerebral infarction and cerebral hemorrhage are not diseases to be taken lightly. However, the medical community classifies cerebral hemorrhage as a much more serious disease. In Korea, the death rate from cerebral hemorrhage is slightly lower, at around 20%, but worldwide, the death rate is said to be around 40-50%. Ironically, the death rate from cerebral hemorrhage is high in Western countries. The reason is said to be mainly due to genetic background.
So what symptoms and problems does a stroke cause? Stroke symptoms are said to appear locally. When a cerebral infarction occurs, the whole brain does not die, but only part of it, and a cerebral haemorrhage causes only part of the brain to die.
This means that localized neurological symptoms occur, such as sudden paralysis in the limbs but only on one side, or loss of language (functioning) among all cognitive functions.
Previously, genetic background was mentioned as the reason for the high death rate from cerebral hemorrhage in Western countries. It also raises questions about whether genetic factors, or family history, are an important risk factor.
Professor Seunghoon Lee’s answer is surprising. Professor Seunghoon Lee’s point of view is, “Ignore family history.” Of course, there are two representative genetic diseases related to stroke. These are Cardasil disease and Moyamoya disease. Both of these diseases require awareness of family history and can even be inherited.

The reason why Professor Seung-Hoon Lee expressed a lenient stance on family history is because stroke is a disease where the risk of exposure increases with age and aging. In addition, five things that are considered definite risk factors for stroke appear to have been considered.
The five obvious risk factors are ‘hypertension, hyperlipidaemia, diabetes, tobacco and alcohol.’ Among them, high blood pressure is said to be a high risk factor for cerebral infarction and cerebral hemorrhage. Diabetes and hyperlipidemia are said to be more important factors in cerebral infarction than cerebral hemorrhage. Speaking of stroke, it seems that the reason it becomes more dangerous when the weather is cold is because of high blood pressure.
Professor Seung-Hoon Lee says, “In many cases, people cause strokes themselves.” It appears to be due to cigarettes and alcohol, which are easily overlooked. Above all, cigarettes are said to affect cerebral infarction and cerebral haemorrhage. Interestingly enough, while alcohol has a protective effect against cerebral infarction, it is a strong risk factor for cerebral haemorrhage.
So, Professor Seung-Hoon Lee says, “Whenever a patient has a brain infarction and asks what to do with their drinking, I tell them, ‘You can drink it in moderation.'” By course, the advice is that it is best to control the five risk factors, including alcohol, as much as possible. They say that measures are needed to control high blood pressure, hyperlipidemia, and diabetes and to reduce alcohol consumption. And you should stop smoking.
Professor Seung-Hoon Lee said, “Actually, stroke is the result of various diseases, so it doesn’t just happen without other diseases. Ultimately, there are five definite risk factors, so we have to make a detailed diagnosis and manage it even on a daily basis.”
